SBS2008 Outlook continually prompting for username/pw after email domain change
Posted on 2012-09-07
I think i made a boo boo.
I have a small office with an SBS2008 box and six or so users, running Outlook (2007 or 2010).
Recently they wanted to change their primary email domain name from the one set up with SBS.
So, I ran the Set up your Internet Address wizard again, and put in the new domain.
This changed everything in exchange, so their primary emails were now correct. I also added in the original email via the Exchange Management Console so they could receive email on that address too.
Anyway email delivery has no problem. However, all Outlook clients are constantly getting a popup for their username and password. If they put inthe details it goes away for 10 mins or so, then appears again. Email still flows even if they cancel the box, it seems an annoyance more than anything but its REALLY annoying.
Anyway, to resolve it I've tried many things including running the certificate wizard again (they have a self signed cert) and confirming the certificate has the new domain in it, i've manually forced the install of the new certifiacte via internet explorer on all the clients, I've installed Exchange 2007 SP2, I've deleted and re-created the exchange account in outlook, i've turned off Exchange over HTTP on all local office clients outlook.
Where else should i be looking?
